 Related to the addition of new services to the Attributes table, is there a way to check if a certain service UUID has already been added? 
 This problem arose because I have two modules that are supposed to use the same service, but are unaware</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Thu, 25 Oct 2018 13:15:48 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/39492/check-if-a-certain-service-uuid-has-already-been-added" /><item><title>RE: Check if a certain service UUID has already been added</title><link>https://devzone.nordicsemi.com/thread/154518?ContentTypeID=1</link><pubDate>Thu, 25 Oct 2018 13:15:48 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:fd2ea72d-5c0d-4e15-b7c5-33c61706acfa</guid><dc:creator>Mttrinh</dc:creator><description>&lt;p&gt;Have a look at this &lt;a href="https://devzone.nordicsemi.com/f/nordic-q-a/12539/multiple-services-issue" rel="noopener noreferrer" target="_blank"&gt;post&lt;/a&gt;, I think this is the reason one of the service&lt;span&gt;&amp;nbsp;has the data characteristics, while the other one is empty.&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Check if a certain service UUID has already been added</title><link>https://devzone.nordicsemi.com/thread/153509?ContentTypeID=1</link><pubDate>Thu, 18 Oct 2018 15:03:46 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:b7f151a0-4538-405f-a994-48859960b82f</guid><dc:creator>AmiguelS</dc:creator><description>&lt;p&gt;Hello!&lt;br /&gt;&lt;br /&gt;Our application makes use of two software modules (running on the same nRF5 device), that were design to be, well... modular. So they both use the same service, but do not communicate between themselves, so they have no way of knowing if a certain service has already been added to the attribute table. This leads to duplicated entries on the table, as both module initialize the same service.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Check if a certain service UUID has already been added</title><link>https://devzone.nordicsemi.com/thread/153506?ContentTypeID=1</link><pubDate>Thu, 18 Oct 2018 14:56:32 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:f4ccbf02-a527-40bc-a228-dc7138c0f3fd</guid><dc:creator>Mttrinh</dc:creator><description>&lt;p&gt;Hi,&lt;/p&gt;
&lt;p&gt;Unfortunately, there isn&amp;#39;t a way&amp;nbsp;&lt;span&gt;to check if a certain service UUID has already been added.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;I&amp;#39;m not sure I understand your issue, can you give me more details? When you say two modules, do you mean two devices?&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
